The Lord of the Rings RPG: Tales from Eriador

Now they had gone on far into the Lone-lands, where there were no people left, no inns, and the roads grew steadily worse. Not far ahead were dreary hills, rising higher and higher, dark with trees. On some of them were old castles with an evil look, as if they had been built by wicked people.

Tales From Eriador is a beautifully illustrated hardback compendium containing six adventures for The Lord of the Rings™ Roleplaying, the 5E adaptation of the The One Ring™ tabletop roleplaying game based on the works of J.R.R. Tolkien. All set in the lone-lands of north-western Middle-earth, the adventures can be played individually, or as part of a larger tale.

A Troll-Hole, If Ever There Was One and Kings of Little Kingdoms are both relatively self-contained adventures, but still hint at a growing danger.
Messing About In Boats involves directly one member of the Company, in an unexpected way!
Not To Strike Without Need and Wonder of the Northern World follow the slow infiltration of spies of the Enemy.
Finally, The Quest of Amon Guruthos challenges the heroes to battle an ancient evil.
